Pass the Netapp NCIE-Data Protection NS0-528 Questions and answers with ValidTests

Each node in a NetApp cluster must have at least one Intercluster LIF to participate in SnapMirror replication. Therefore, for a six-node cluster (primary), you need six LIFs, and for a two-node cluster (secondary), you need two LIFs — one per node.

To enable tamper-proof (locked) Snapshot copies using SnapLock, the SnapLock Compliance Clock must be initialized on all nodes in the cluster. Without initializing this clock, locked Snapshots cannot be created, even if the policy and retention settings are configured.

NetApp BlueXP simplifies data protection across hybrid multicloud environments by enabling:

● One-click failover, failback, and resync operations, which streamline disaster recovery workflows.

● Drag-and-drop replication, which provides an intuitive interface to easily create SnapMirror relationships between on-prem and cloud-based ONTAP clusters.

SnapMirror Asynchronous is designed to replicate data based on a scheduled interval, such as once per hour. It is ideal for disaster recovery scenarios where zero RPO is not required but periodic replication is sufficient.

To achieve granular control over SnapLock Compliance behavior:

1. Set the default retention period to "unspecified", so files are not automatically locked.

2. Disable autocommit and instead manually commit only the specific files that should be locked, allowing precise control over what is protected and when retention starts.

When multiple databases are stored on the same LUN and a single database needs to be restored using SnapMirror active sync, the restore process must target the specific byte range corresponding to that database. This requires the starting byte offset and the ending byte offset.

These define the exact data region on the LUN to be restored without affecting the other databases.

To create application-aware backups of SAP HANA databases:

● You must install the SnapCenter Plug-in for SAP HANA, which provides database-consistent backup and restore operations.

● You must also create a backup policy that aligns with the customer's retention requirements to manage how long backups are kept and how often they’re performed.

Autonomous Ransomware Protection (ARP) is a native NetApp ONTAP feature that uses machine learning to monitor and analyze file activity patterns. It detects anomalies such as sudden spikes in file changes — typical of ransomware behavior — and automatically alerts or blocks access to limit potential damage.

After setting up a SnapMirror active sync relationship, to ensure automatic failover in case of site failure, you must:

● Map the LUNs on the secondary site, so they are accessible during a failover.

● Change the service policy on the SAN LIFs to enable multipathing and ALUA support, ensuring paths are correctly managed between primary and secondary sites.

SnapMirror active sync provides active-active synchronous replication for SAN workloads (including FC-attached databases), ensuring zero RPO and near-zero RTO. It enables automatic failover and failback between sites, making it the ideal solution for mission-critical applications requiring continuous availability.
